this is a thing:
Stances Regarding Regulation - The Liberal Gun Club
I'm not a member, but I would consider myself left-leaning in social issues, and I like guns. And I get really frustrated when politicians take a stance without having even basic knowledge of firearms. It totally destroys their credibility.
also,
44% of republicans own a gun, and for democrats, it's 20%. That's quite a lot of dems, IMO. As usual, the general public is not as partisan as the politicians make it seem.
The Fort Knox PB1 is a mechanical 5-button Simplex combo lockbox for pistols:
Fort Knox Original Pistol Safe (PB1) | FTK-PB
It has holes in the base so you can mount it to something. That leads me to think that it can be bolted securely to some part of the car's frame, most likely in the trunk.
